Development/Plugins

Plugins Demo1

I'm writing these docs while trying to write my 1'st plugin. And it's easiest to write docs the 1'st time you use something. So these docs will not follow best practices because of lack of experience

Purpose

Setting up a base plugin and adding a status-field.

This plugin adds a status-field and a setter to the core.

It does not save the state,and all information is lost after a restart of the daemon.

Test code:

from deluge.ui.client import sclient
sclient.set_core_uri()
id = sclient.get_session_state()[0] #1st torrent

print "before:",id, sclient.get_torrent_status(id, ['name','label'])

sclient.label_set_label(id,'')
print "after reset:",sclient.get_torrent_status(id, ['name','label'])


sclient.label_set_label(id,'movie')
print "after set:",sclient.get_torrent_status(id, ['name','label'])

Desired Result:

before: f2b609578473f6a29d3123ba0897213b3c1bbcda {'name': 'aesmsclient_0.2.1.jar', 'label': ''}
after reset: {'name': 'aesmsclient_0.2.1.jar', 'label': ''}
after set to 'movie': {'name': 'aesmsclient_0.2.1.jar', 'label': 'movie'}

eggs

The good and bad news about deluge 0.6 plugins is that it uses eggs. Deployment of eggs is easy, but they do need some meta-data.

We're not addressing deployment now, eggs support directory based development too. And IMHO it's easier to develop with directory's than with zipped eggs

Minimal structure of a deluge plugin directory:

name.egg/
name.egg/EGG-INFO
name.egg/EGG-INFO/PKG_INFO
name.egg/EGG-INFO/entry_points.txt
name.egg/name/
name.egg/name/__init__.py
name.egg/name/core.py

Meta data

Real code

# adds a status-field,does not remember settings after restart of daemon.

from deluge.log import LOG as log

    def enable(self):

        # Register the 'label' status field
        self.plugin.register_status_field("label", self._get_label)        
        log.debug("Label plugin enabled..")
    
    def disable(self):
        # De-register the label field
        self.plugin.deregister_status_field("label")

    def update(self):
        pass
            
    ## Status field function ##
    def _get_label(self, torrent_id):
        #return label or empty string.
        return self.labels.get(torrent_id, '')
        
    ## Setter ##
    def export_set_label(self, torrent_id, label):
        log.debug("set label %s=%s" % (torrent_id, label))
        self.labels[torrent_id] = str(label)
